Attic AC

Well, I want to install AC in my attic for a 2300 square foot ranch. Looked into Hi Velocity turned off by the reduction in seer rating. So thinking conventional. Not an avid fan of flexible ductwork. Just wondering about the pvc duct work, an avenue that went through my head knew there must be a reason why not widly used.

I have read alot about ductwork in unconditioned spaces. I know its not my best option. But its doable. If done right. I have ceiling radiant heat (hydronic). My concerns with the ductwork would be A. Condensation in the winter or summer, leading to mold issues. B. Lack of performance, ductwork being warm/ hot between cooling cycles leading to longer than needed cycles.

This system would only be for AC. So I'm tryin to get my ducks in row here. Thinking of using two air handlers so I can keep my attic center unobstucted for storage. The ranch is a U shape. HeatGain 40,000 Btu high side. I presently use 30,000 Btu's worth of window shakers and it cools they handle the load.

any kind of ductwork can be done. it depends how thick your wallet is. i would use standard galvanized metal that would get wrapped on the outside. i too dislike flex systems, Dash would disagree with me.
